Should I go to the emergency room, see my family doctor, or just take some advil?

If you are experiencing mild chest tightness after receiving the second dose of the Pfizer vaccine, you may consider taking Advil if you do not have any contraindications. However, if the chest tightness is causing intense pain, difficulty breathing, or any other discomfort, it is recommended to seek medical attention. Monitoring any symptoms for a few days after the vaccine and seeking help if needed is important. Remember that everyone may experience different side effects, so it's best to listen to your body and seek medical advice if necessary.
